1383 Remove the next field from AVFilter, this is not anymore required.
1385 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1386 Introduce the avfilter_next() function.
1388 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1389 Change the signature of avfilter_register() to make it return an
1390 int. This is required since now the registration operation may fail.
1392 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1393 Make the pixdesc.h API public.
1395 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1400 Add a description field to AVFilter.
1402 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1403 Change the interface of avfilter_make_format_list() from

1417 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1418 Add a pts field to AVSubtitle which gives the subtitle packet pts
1419 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1420 not work right without this.
1422 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1423 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1424 major version. Use AV_PKT_FLAG_KEY instead.
1426 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1427 av_lockmgr_register() can be used to register a callback function
1428 that lavc (and in the future, libraries that depend on lavc) can use
1429 to implement mutexes. The application should provide a callback function
1430 that implements the AV_LOCK_* operations described in avcodec.h.
1431 When the lock manager is registered, FFmpeg is guaranteed to behave
1432 correctly in a multi-threaded application.
1434 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1435 av_free_packet() is no longer an inline function. It is now exported.
1437 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1438 Please use NULL instead. This has been supported since r16506
1439 (lavf > 52.23.1, lavc > 52.10.0).
1441 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1442 The old decoding functions are deprecated, all new code should use the
1443 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1444 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1445 argument instead of a const uint8_t *buf / int buf_size pair.
1447 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1448 Introduce the av_fifo_space() function.
1450 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1451 Move AVPacket declaration from libavformat/avformat.h to
1452 libavcodec/avcodec.h.
1454 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1455 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1456 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1457 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1458 PIX_FMT_BGR32_1 are now macros.
1459 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1460 Re-sort the enum PixelFormat list accordingly.
1461 This change breaks API/ABI backward compatibility.
1463 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1464 Add the enum PixelFormat values:
1465 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1466 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1468 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1469 The Mersenne Twister PRNG implemented through the av_random* functions
1470 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1473 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1474 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1475 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1476 and av_fifo_realloc2.
1477 In addition, the order of the function arguments of av_fifo_generic_read
1478 was changed to match av_fifo_generic_write.
1479 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1480 applications, they may not use sizeof() or directly access members.
1482 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1483 Introduce a new metadata API (see av_metadata_get() and friends).
1484 The old API is now deprecated and should not be used anymore. This especially
1485 includes the following structure fields:
1486 - AVFormatContext.title
1487 - AVFormatContext.author
1488 - AVFormatContext.copyright
1489 - AVFormatContext.comment
1490 - AVFormatContext.album
1491 - AVFormatContext.year
1492 - AVFormatContext.track
1493 - AVFormatContext.genre
1496 - AVProgram.provider_name
